UnitFlag

Unit flags contain information for a unit in the combat log. They are returned from COMBAT_LOG_EVENT and params.

A unit can only be one type from each of the following four categories:

• 1) Type: The way the unit is currently being controlled.
• 2) Controller: Who currently controls this unit - an NPC or a player.
• 3) Reaction: The unit's reaction, relative to you - hostile, friendly or neutral.
• 4) Affiliation: If the unit belongs to you (your character, pet, mind controlled) or is in your party or raid, or neither.

• A player who was mind controlled by another player that attacks you is (A hostile outsider pet controlled by a player)
• Since can also be an enemy player's pet you need to check the unit GUID to know if it's an enemy pet or a player character.
